INKING-PAD.

Specification of Letters Patent.

Patented Dec. 2, 11am.

Application filed July 23, 1919. Serial No. 312,833.

To all whom it may concern:

Be it known that I, CHARLES H. PAYNE, a citizen of the United States,residing at the city of Cincinnati, in the county of Hamilton and Stateof Ohio, have invented certain new and useful Improvements in Inking-Pads, of which the following is a specifi- The object of my invention isto produce a cheap, simple, highly efficient and sanitary inking pad,belonging to that class of pads upon which the ink is placed and uponwhich the rubber, metal or other die or stamp is pressed to be coatedwith ink, or over which the stamp or die passes during its movement.

Stamps and inking pads of thischaracter are usually made of felt, wovenfabric of some kind or a padded part covered with linen or muslin orsuch fabric. These pads dry out and become stiff and hard, the face ofsuch pads gives up. particles of the fabric, which attach to the stampor die and form improper impressions and they do not distribute the inkuniformly; they are unsanitary and can not be washed and cleaned.Suchpads lack resiliency and have no cushion like effect. Pads of thischaracter having no inherent resiliency do not properly and evenlydistribute the ink and when the stamp is used some of the letters or theimpression is dim and the other part of the impression is bold, thusproducing an undesirable result. Pads of this kind also wear into a rutor depression when often struck in the same place.

After making many experimentsto evolve a pad which would overcome allthese objections and have the features and advantages desired and neededin such an article, I have discovered that a product known as .spongerubber, properly treated, will form an ideal inking pad, for the reasonsthat it is cheap, clean, sanitary, has an inherent resiliency,distributes the ink over the face of the die or stamp evenly, wears welland is not affected by the changes of temperature and will not readilywear uneven or into a depressed form in spots or sections and will notbecome stifl, brittle and stringy or stale, tive and fresh for service,and on account of the uniform distribution of the ink, the impressionwill be enhanced in appearance.

In the accompanying drawing forming part of this specification:

Figure 1, is an isometric view of one of my new pads, without ink,

Fig. 2, is a similar view with the ink shown therein,

Fig. 3, is a view similar to that shown in Fig. 1, except that a lid orcover is attached to the pad body,

Fig. 4, is an isometric vieW of a number of the single pads placed oneon top of the other, to form a pile,

Fig. 5 is an isometric view of a single pad with a metal or other basepiece,

Fig. 6 is an isometric view of my new pad in the form of a roller orcylinder, and

Fig. 7, is a broken view of pad showing solid edges.

In carrying my invention into effect, I usually form a rectangular pad1, as shown in Figs. 1 2, 3 and 5, but may make the same roun as shownin Fig. 4, or in cylin drical shape, as shown in Fig. 6; however,claiming the right to make it of any size, shape or contour.

In the present instance, it is made of what is known as sponge rubber orits equivalent, or a material of an analogous nature.

Usually, in forming the pad, the upper or side which receives the ink 2is buffed or roughened so that the ink will properly permeate the padand act as a resilient face to receive the inking stamp or die which ispressed upon it to receive the ink; this surface may be formed in thisway in any manner or may be molded or cast to form such a face as justdescribed, that is, one with the pores properly and satisfactorilyopened to receive the ink as heretofore described. This pad may beformed and composed entirely as the face thereof is formed, or its underside may be of greater density, or I even may place a smooth surfacerind at the bottom to give the pad a uniform and smooth foundation.

In Fig. 3, I show a lid or cover as 3 atbut will always be ac- 'getherby placing substance along the peripheral edges pads.- In Fig. 5, I showthe pad I placed in a base 4 made of metal or a similar mate-v rial,shaped so that it may be placed in some machine or device upon which, orin connection with which, some rubber or other die or stamp operates. InFig. 6, I show my pad in a cylindrical form placed around a metal rolleras 5 which can be used in the manner in which stamps of this form areusually employed. The roller 5, base 4 and the lid 3 may be made of anvsuitable materlal and attached to the pad part in any preferred mannerfound best in practice. I may form the base 4: so that it will entirelycover sides and ends of the pad 1 and may, if desired, also attach thecover 3 thereto and make these parts of any other shape and form thanherein set forth.

In Fig. 7, I show a band of rubber or analogous material placed aroundthe edges of the pad body 1, and designated by numeral 9 and this may bea formation similar to the rind 8, if desired. Its use strengthens thepad body, enhances its appearance and keeps any surplus ink from oozingout at the sides and ends of the pad, if perchance the pad carried toomuch ink.

It will be readily obvious and understood that all the advantages setforth herein are present in my new pad and that it forms an article ofmanufacture having the advantages of great desideratum; that it is noveland unique; that it can be placed upon the market cheaply and that itcan be used for a long time without deteriorating.

It do not wish to limit myself to the article known as sponge rubber,though preferring the same, I may use any material of an analogousnature which will answer the purpose andresult in the advantage hereinset forth.

What I claim as new and my invention and desire to secure by LettersPatent, is

1. As a new article of manufacture, an inking pad, formed of spongerubber or equivalent material.

2. An inking pad, formed of a sponge like rubber material havinganinherent resiliency.

3. An formed of sponge like rubber material.

4. An inking pad, having a porous face formed of spon e like, rubbermaterial, increasing in dens ty at the base.

a 5. An inking pad formed of a sponge like rubber material provided witha porous face surface.

6. An inking pad, formed of a resilient sponge like rubber material.

An inking pad, formed of a multipl clty of separate pads, one resting onthe other, each having an inherent degree of reinking pad having aporous face' siliency and formed of a rubber material and each providedwith a porous face.

8. An inking pad, having a porous face of rubber material and possessingan inherent resiliency and a supporting base for same.

9. An inking pad, having a porous face of rubber material and possessingan inherent resiliency and a supporting base for same, and a hingedcover attached thereto.

10. An inking pad, formed of a resilient sponge rubber having a faceformed of a network of pores to receive the inkv 11. An inkin pad.formed of resilient rubber material, having a face formed of a multitudeof small pores to hold the ink and to retain the same within the bodypart of the Dad 12. An inking pad having a resilient porous ink holdingsurface, formed of yieldable rubber material.

13. In an inking pad, a bodv made of sponge rubber material providedwith solid edges.

In ture at Cincinnati, July, 1919.

testimony whereof I afiix my signa- Ohio, this 21st day of CHARLES H.PAYNE.
